C# to Dart Model Generator

Convert C# DTOs and model classes directly into clean, complete Dart classes with fromJson and toJson serialization in Visual Studio Code.

Easily copy a C# model from backend projects, Swagger, or web pages, and paste it as ready-to-use Dart code directly into your code editor.

Features

• Paste C# as Dart (Ctrl + Alt + V / Cmd + Alt + V): Detects C# code in your clipboard, converts it to a Dart model, and pastes it at your cursor position instantly.
• Convert Selection: Converts highlighted C# code directly in the active editor.
• Context Menu Integration: Right-click in the editor and choose Paste C# as Dart.
• Complete Dart Code Generation:
  • final fields
  • Named required parameters in constructor
  • Type-safe factory Model.fromJson(Map<String, dynamic> json)
  • Map<String, dynamic> toJson()
  • Generic support with fromJsonT and toJsonT for generic models like ResponseDto<T>
  • Full support for nullable types, lists, nested DTOs, dictionaries (Map), and DateTime parsing
  • Smart camelCase naming conventions for properties (handles underscores and acronyms properly)

How to Use

1. Copy any C# class to your clipboard (Ctrl + C / Cmd + C).
2. Open your .dart file in Visual Studio Code.
3. Move the cursor to where you want to insert the model.
4. Paste using any of the following methods:
   • Keyboard Shortcut: Ctrl + Alt + V (macOS: Cmd + Alt + V)
   • Right-Click Context Menu: Right-click in the editor and select Paste C# as Dart.
   • Command Palette: Press Ctrl + Shift + P (macOS: Cmd + Shift + P) and type Paste C# as Dart.

Example Conversion

Input C# Code (Clipboard):

public class UserDto
{
    public int Id { get; set; }
    public string Username { get; set; }
    public string Email { get; set; }
    public bool IsActive { get; set; }
}

Generated Dart Code:

class UserDto {
  final int id;
  final String username;
  final String email;
  final bool isActive;

  UserDto({
    required this.id,
    required this.username,
    required this.email,
    required this.isActive,
  });

  factory UserDto.fromJson(Map<String, dynamic> json) {
    return UserDto(
      id: json['id'] ?? 0,
      username: json['username'] ?? '',
      email: json['email'] ?? '',
      isActive: json['isActive'] ?? false,
    );
  }

  Map<String, dynamic> toJson() {
    return {
      'id': id,
      'username': username,
      'email': email,
      'isActive': isActive,
    };
  }
}
